The correct reasoning for the water filtration technology to choose would be:
Reverse osmosis because it requires low maintenance, and removes all contaminants such as bacteria and chemicals.
This option accurately portrays reverse osmosis as a reliable method for filtering out a wide range of contaminants, including bacteria and chemicals, while also highlighting its low maintenance needs.
However, it's worth noting that while reverse osmosis is effective, it does require filters and some maintenance. Therefore, it's important to consider the family's specific water quality needs, maintenance preferences, and budget limitations before making a final decision.
